SVG渐变不起作用

问题描述

我有一个svg，我需要用渐变填充，css是由脚本添加的，如果U使用单一RGB颜色，则都可以正常工作，但是使用渐变，SVG会产生白色背景.

I've a svg and I need to fill it with a gradient, the css is added by a script, if U work with a single RGB color it all work fines but with a gradient the SVG results in a white background.

脚本后的结果代码:

<svg xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1"
id="Livello_1" x="0px" y="0px" viewBox="0 0 70 70"
style="enable-background:new 0 0 70 70;width: 50px; height: 50px;"
xml:space="preserve">
<defs>
  <lineargradient id="grC29M" x1="0%" y1="0%" x2="100%" y2="0%">
    <stop offset="0%" style="stop-color:rgb(88,88,88);stop-opacity:1"></stop>
    <stop offset="100%" style="stop-color:rgb(255,255,255);stop-opacity:1"></stop>
    </lineargradient>
</defs>

<path class="st0" d="......" style="fill: url("#grC29M")">
</svg>

谢谢！

推荐答案

当此渐变不起作用时，我在chrome中遇到了一个非常奇怪的错误

I had a very strange bug in chrome when this gradient didn't work

    </defs>
</svg>

直到我将id从 paint0_linear 和 paint1_linear 更改为 gradient1 和 gradient2 .

until I've changed the ids from paint0_linear and paint1_linear to gradient1 and gradient2.

一个很奇怪的问题，但这也许会对某人有所帮助

Quite a strange issue, but maybe this will help someone
